87-255 50 mm Dia. Hard Coated Quad-Band Fluorescence Bandpass Filter; t=2 mm 440/521/607/700nm

The 87-255 is a Quad-Band Fluorescence Bandpass Filter, sourced from the reputable optical components vendor, Edmund Optics. This filter, with a diameter of 50 mm and a thickness of 2 mm, is designed for use in a variety of applications that require precise wavelength selection.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It has a cut-on wavelength of 420 nm and a cut-off wavelength of 460 nm, with a central wavelength (CWL) of 440 nm. This means it allows transmission of light within the 440 nm range while blocking light outside this range.

The 87-255 filter features hard coating on both the front and back surfaces, denoted as 'edm 87-239'. This coating enhances the filter's durability and resistance to wear and tear, making it suitable for use in harsh environments.

The filter's geometry is in the shape of a thin lens, which is often used in optical systems to bend light and focus it onto a specific point. This feature, combined with its quad-band properties, makes the 87-255 a versatile and valuable component in fluorescence microscopy, spectroscopy, and other applications that require precise wavelength control.
